All the films listed and discussed in Occultism, Hauntology and the Urban 'Wyrd', which is chapter 5 of Folk Horror: Hours Dreadful and Things Strange.
"Hauntology presents Britain in the 1970s as a place of skewed morality, of isolated Brutalist zones, of the 'Urban Wyrd' and of paranoid, dystopian deulsions surrounding the treatment of women and children. In other words, Hauntology shows the decade in its true guise; not just the place where Folk Horror was produced most abundantly but itself the most terrifying form of Folk Horror conceivable." - Adam Scovell
